The interview started with a Zoom call. The interviewer was unfriendly and started without even asking my name or any greetings. He asked very difficult questions about NLP and ML questions and laughed at me when I couldn't answer a question. The whole experience was really stressful and unpleasant. After this interview, four programming questions (including coding an autoencoder with PyTorch) were sent to me with only 75 minutes to send back the answers.
